Methods for Improving Drug Delivery to the Central Nervous System

    The invention relates to the uses of the tricyclic antidepressant 
amitriptyline, its bioactive metabolites, and other LPA1R activators to 
improve the bioavailability and delivery of therapeutics to the central 
nervous system. This invention demonstrates that amitriptyline and 
other agents selectively decrease P-glycoprotein (P-gp) transport 
activity by ligand activation of lysophosphatidic acid 1 receptor 
(LPA1R) at the blood-brain barrier. P-gp is an effective target for 
increasing drug delivery to the brain (CNS) for two major reasons: (1) 
Its substrates include a large portion of on-the-market drugs, 
including chemotherapeutics, and (2) its directionality results in a 
net efflux of drugs from the brain. Additionally, specifically 
targeting P-gp through LPA1R activation bypasses the clinical 
challenges resulting from the toxicity of substrate inhibitors of P-gp. 
This invention describes the inhibition of drug efflux by P-gp 
transport; thus, co-administration of therapeutics with amitriptyline 
and other LPA1R activators provides a method for increasing drug 
delivery to the CNS, and improving overall drug efficacy. Moreover, 
drug delivery to other barrier tissues will also be enhanced where a 
similar LPA1R-P-gp activity relationship exists.
    Potential Commercial Applications:
     Drug Delivery to the CNS.
     Co-administration of therapeutics.
     Blood-brain-barrier permeability.
    Development Stage:
     Early stage.
